 This is very true, at least for the M68K assemblers that I know of. Nor
have I seen such a thing in x86 assemblers (less knowledge).
But: SECTION's (a program data/code "hunk" - in Amiga terms) can be set to
readonly - which _may_ be enforced depending on set assembler options (i.e.
to generate stuff for ROM).
